我厂产品光譜仪中的精密絲杆,要求精度較高,螺距1毫米,螺紋半角30~(°±20′),光洁度▽▽▽_7。車床加工由于缺少对刀装置,达不到半角精度要求。老工人呂蟃鐾靖慕塑嚨度屑屑岸缘斗椒?解决了这个技术关鍵。如附图,車刀刀夹6是一个固定在四方刀架上的可調刀架,刀槽內装螺紋車刀,刀柄上做有半圓鍵5(或把半圓鍵装在槽內右壁正中)。槽外左壁装两只調节
Precision screw rod in our product spectrometer requires high precision, pitch 1 mm, thread half angle 30 ~ (° ± 20 ’), finish ▽ ▽ ▽ _7. Lathe machining due to the lack of alignment device, can not reach the half-precision requirements. The old worker Lu 蟃 鐾 Jing Mu plastic throat crumb shore edge of the pepper? Solved the key technology. As shown in the figure, the lathe tool holder 6 is an adjustable turret fixed on the square turret. The lathe is equipped with a thread turning tool, and the semicircle key 5 is made on the shank (or the semicircle key is mounted on the right wall of the groove middle). Outside the tank installed two left adjustment
